I would also like to do a platinum challenge. There might be a problem though. I"m gold, from SPG match. but it seem I also have current gold challenge I didn't know about. Back in Nov I called about a stay mid Nov I had (3 rooms 1 night + 1 room 2 nights) about the MR numbers assigned to the rooms. The agent suggested the gold challenge. I told him I wouldn't be using hotel nights until late Jan. I called today about it and I seem to in a gold challenge until Feb 28th and oddly the agent said I had 3 stays already. I have used reward for my upcoming stay at the RC in Cancun. and one night that was purchased through American Express Travel which shouldn't count. Is there some thing I can do to get a platinum Challenge. I have 6 stay already in the schedule before the end of March.
